The client library had several issues preventing operations from completing in the simulation: - toastyfs_register_events discarded the computed timeout instead of returning it to callers, so clients never woke up on schedule - random_client_tick ignored the timeout parameter entirely - deadline_to_timeout truncated sub-millisecond values to 0 instead of rounding up, causing busy-wait loops - The server didn't reset the heartbeat timer after completing a view change, so followers would immediately timeout again - The client's DELETE handler didn't handle META_RESULT_NOT_FOUND, causing an assertion failure when deleting non-existent keys - Most critically, messages sent before TCP connections were established were silently dropped with no retry mechanism — added timeout-based retry logic in toastyfs_process_events https://claude.ai/code/session_0184gHjra7fsmSPZ4kppaGhC
